Home Page</A><BR>
Information about CD-ROM databases of ECGs and other physiologic signals,
and related software.
<LI><I><A HREF="/physiotools/wpg/">WFDB Programmer's Guide</A></I>
<BR>
Includes tutorial and reference material relating to the WFDB library,
a portable set of functions (subroutines) for reading and writing files in the
formats supported by the applications described here.  The WFDB library may be
used with C, C++, or Fortran programs;  the guide primarily describes the C
interface.
<LI><I><A HREF="/physiotools/wag/">WFDB Applications Guide</A></I>
<BR>
Includes <TT>man</TT> pages for the applications included in the WFDB Software
Package, specifications for file formats supported by the DB library.  Detailed
installation instructions for the WFDB Software Package are included in an
appendix, and a second appendix discusses how the performance of ECG analyzers
can be formally evaluated using standard reference databases and the standard
evaluation tools included in the WFDB Software Package.

A comprehensive tutorial, with extensive reference material, for
<STRONG>WAVE</STRONG>, an interactive waveform browser with facilities for
annotation editing and control of external analysis programs.
<STRONG>WAVE</STRONG> runs on PCs under the free Linux operating system, and
on SPARC-based systems under SunOS or Solaris.
